Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0039] Currently, the electric drive systems of new energy vehicles are rapidly developing toward high power density, low cost, high integration, and high efficiency. This trend requires high power density and compact motors. Electric drive systems for new energy vehicles typically integrate a motor and a reducer. The motor's output shaft works with the reducer, reducing the motor's rotation and outputting power. Both the motor and reducer are mounted within the electric drive system's housing, while the controller is separately installed within the controller housing. The controller housing must be sealed to ensure it meets the required protection level, and then the controller housing is assembled and connected to the electric drive system housing.

[0040] However, since the controller is installed separately in an independent shell space, the controller shell is installed on the motor shell after the overall assembly and testing of the controller is completed. The existing structure and space on the motor shell cannot be utilized. The overall structure of the electric drive system occupies a large space and is heavy.

[0041] In response to the above problems, an embodiment of the present application provides an electric drive system and a vehicle. Through the structural design of the motor housing, the controller housing and the motor housing are integrated, so that the controller can utilize the structure of the motor housing during assembly, thereby reducing the overall volume of the electric drive system and reducing the weight of the electric drive system.

[0042] The technical solution of this application will be described in detail below through specific embodiments.

[0043] Figure 1 A schematic diagram of the structure of the electric drive system provided in an embodiment of the present application; Figure 2 A cross-sectional view of an electric drive system provided in an embodiment of the present application; Figure 3 An exploded diagram of the electric drive system provided in an embodiment of the present application;

[0044] Figure 4 for Figure 3 Partial view of the A position in the middle; Figure 5 A schematic structural diagram of the second housing in the electric drive system provided in an embodiment of the present application; Figure 6This is a front view of the second shell facing the first shell in the electric drive system provided in an embodiment of the present application.

[0045] like Figures 1 to 6 As shown, an embodiment of the present application provides an electric drive system 10, which includes a first housing 110, a second housing 120, a motor assembly 200, and a controller assembly 500. The first housing 110 has a first accommodating cavity 101, and the motor assembly 200 is disposed in the first accommodating cavity 101. The top of the first housing 110 has an accommodating groove 103. The second housing 120 is disposed above the accommodating groove 103 and, together with the accommodating groove 103, forms a second accommodating cavity 102. The controller assembly 500 is located in the second accommodating cavity 102.

[0046] The controller assembly 500 is connected to the side of the second housing 120 facing the receiving groove 103. When reassembling the controller assembly 500, the controller assembly 500 can be first installed on the second housing 120, and then the second housing 120 with the controller assembly 500 installed is placed on the first housing 110 to complete the assembly and sealing of the controller assembly 500.

[0047] It is understood that the first housing 110 provides a mounting structure and accommodation space for the motor assembly 200, and a portion of the structure on the second housing 120 is integrated with the second housing 120 to provide an accommodation cavity space for the controller assembly 500. The housing for the controller assembly 500 can utilize a portion of the structure of the first housing 110, so that the controller assembly 500 and the motor assembly 200 are integrated during the assembly of the controller assembly 500.

[0048] The first housing 110 and the second housing 120 are directly opposite and sealed, so that the controller assembly 500 meets the protection level requirements required by the vehicle.

[0049] It should be noted that in the electric drive system 10 provided in the embodiment of the present application, the housing of the motor assembly 200 is provided by the first housing 110, and the housing of the controller assembly 500 is provided by the first housing 110 and the second housing 120. The first housing 110 and the second housing 120 are assembled and connected together to realize the integration of the housing of the controller and the housing of the motor assembly 200. The assembly of the controller assembly 500 is completed by docking the first housing 110 and the second housing 120. The controller assembly 500 is installed on the second housing 120, and the setting of the controller assembly 500 utilizes the accommodation space on the first housing 110, thereby reducing the volume of the electric drive system 10 and reducing the weight of the electric drive system 10.

[0050] First, the specific structure of the docking assembly of the first shell 110 and the second shell 120 will be described in detail below.

[0051] Please continue to refer to Figures 1 to 6 In a possible implementation, a protrusion 104 is provided on the outer side of the top of the first housing 110 , and the protrusion 104 surrounds the receiving groove 103 . The contour of the protrusion 104 matches the contour of the second housing 120 .

[0052] It is understood that the raised portion 104 can be annular in shape at the top of the first housing 110. The first housing 110 is placed over the raised portion 104 above the first housing 110 from above the second housing 120. The circumferential edge of the second housing 120 is in contact with the raised portion 104. When the second housing 120 is connected to the raised portion 104, the controller assembly 500 is at least partially located within the accommodating groove 103.

[0053] In some embodiments, the electric drive system 10 may further include a seal disposed around the circumferential edge of one of the raised portion 104 and the second housing 120. A sealing groove 1041 is provided on the circumferential edge of the other of the raised portion 104 and the second housing 120, and the seal abuts against the sealing groove 1041. This improves the sealing performance of the space where the controller assembly 500 is located, ensuring that the controller assembly 500 meets the required level of protection.

[0054] For example, the sealing groove 1041 may be provided on the raised portion 104 or on the second shell 120 , and this embodiment of the present application does not impose any specific limitation on this.

[0055] It is understood that the seal can be bonded to the circumferential edge of the second housing 120 via a sealant. The sealing groove 1041 can be a stepped structure at the top inner edge of the raised portion 104. When the second housing 120 is connected and assembled with the first housing 110, the second housing 120 abuts the raised portion 104, and the seal is compressed between the second housing 120 and the top of the raised portion 104 to achieve a good sealing effect.

[0056] Exemplarily, the sealing member may be an annular sealing ring, and the material of the sealing member may be elastic materials such as rubber and silicone. The embodiment of the present application does not limit the specific material of the sealing member.

[0057] In some embodiments, the protrusion 104 has a sealing surface 1042 disposed around its circumference, and the circumferential edge of the second housing 120 abuts against the sealing surface 1042. The assembly direction of the second housing 120 relative to the first housing 110 is perpendicular to the sealing surface 1042.

[0058] It is understood that the sealing surface 1042 at the top of the raised portion 104 can be a horizontal surface, and the second housing 120 can be assembled from top to bottom relative to the first housing 110. When the second housing 120 and the first housing 110 are in contact and assembled, the seal can be located on the inner side of the sealing surface 1042.

[0059] In some embodiments, the circumferential edge of the protrusion 104 is provided with a first connection portion 1043, and the circumferential edge of the second housing 120 is provided with a second connection portion 121, and the first connection portion 1043 and the second connection portion 121 are opposite to each other. The first connection portion 1043 is fixedly connected to the second connection portion 121 by fasteners.

[0060] It is understood that the first connecting portion 1043 may be a protruding structure on the circumferential outer side of the protruding portion 104, and the first connecting portion 1043 and the second connecting portion 121 may be provided with mounting holes, and both may be screwed together by bolts passing through the mounting holes and nuts to achieve the fixation of the first housing 110 and the second housing 120. Alternatively, one of the first connecting portion 1043 and the second connecting portion 121 may be provided with a mounting hole, and the other may be provided with a bolt hole, and the first housing 110 and the second housing 120 may be fixed together by bolts passing through the mounting holes and screwing together with threaded holes.

[0061] Illustratively, a sealing member 122 is provided on the circumferential edge of the second housing 120 .

[0062] In some embodiments, the outer wall of the first housing 110 has a reinforcing rib 105 connected to the wall of the protrusion 104 facing the interior of the receiving groove 103. The reinforcing rib 105 can improve the structural strength of the first housing 110 and the structural reliability of the protrusion 104.

[0063] There may be multiple reinforcing ribs 105 , and the multiple reinforcing ribs 105 may extend in different directions within the receiving groove 103 , thereby improving the structural strength of the protrusion 104 .

[0064] For example, part of the reinforcing rib 105 may extend in the longitudinal direction of the first shell 110 , and part of the reinforcing rib 105 may extend in the transverse direction of the first shell 110 .

[0065] For example, the reinforcing rib 105 may be integrally formed with the first shell 110 .

[0066] It should be noted that the protrusion 104 and the second housing 120 can be integrally formed. The first housing 110 and the second housing 120 can be made of metal or alloy such as iron or aluminum. The specific material of the first housing 110 and the second housing 120 is not limited in this embodiment.

[0067] Please continue to refer to Figures 1 to 6In one possible implementation, the first accommodating chamber 101 may include a first chamber 101a and a second chamber 101b, with the motor assembly 200 disposed in the first chamber 101a. The electric drive system 10 may further include a reducer assembly 300 disposed in the second chamber 101b.

[0068] It is understood that the inner wall of the first housing 110 serves to mount, secure, and support the motor assembly 200 and the reducer assembly 300. When powered, the motor assembly 200 can output a rotational speed, and the power of the motor assembly 200 can be transmitted to the reducer assembly 300, which is used to reduce the speed of the motor assembly 200.

[0069] In some embodiments, the first chamber 101a and the second chamber 101b are arranged along a first direction. The assembly direction of the second housing 120 relative to the first housing 110 is a second direction. The first direction is perpendicular to the second direction.

[0070] The first direction is defined as an X direction, which may be a horizontal direction, and the second direction is defined as a Y direction, which may be a vertical direction.

[0071] A partition wall 106 is provided between the first chamber 101a and the second chamber 101b. The motor assembly 200 includes an output shaft 210, which extends from the first chamber 101a through the partition wall 106 to the second chamber 101b and docks with the reducer assembly 300. The output power of the motor assembly 200 is transmitted to the reducer assembly 300 through the output shaft 210. Lubricating oil is injected into the second chamber 101b, and when the electric drive system 10 is working, the lubricating oil can lubricate the reducer assembly 300. The partition wall 106 can prevent the lubricating oil thrown up by the reducer assembly 300 from entering the first chamber 101a, thereby ensuring the cleanliness of the working environment of the motor assembly 200.

[0072] In some embodiments, the first housing 110 has a through hole that connects the accommodating groove 103 and the first accommodating cavity 101. The controller assembly 500 may include an electrical connector that is at least partially inserted into the through hole and electrically connected to the motor assembly 200.

[0073] It is understood that the motor assembly 200 may include a three-phase asynchronous motor, and the electrical connector includes a three-phase connector, which is electrically connected to the three-phase asynchronous motor. Thus, when the electric drive system 10 is applied to a vehicle, it can power the three-phase asynchronous motor. The electrical connector may also include a signal line, which can be used to transmit control signals or sensor detection signals. The specific functions of the electrical connector are not limited in this embodiment of the application.

[0074] In one possible implementation, the first housing 110 may include a motor housing and a first end cap 111. The motor housing is configured to form a first chamber 101a, and the sidewall of the motor housing facing the first end cap 111 forms a partition wall 106. The first end cap 111 and the partition wall 106 enclose a second chamber 101b, thereby improving the convenience of housing assembly and reducing production costs.

[0075] It is understandable that the housing may further include a second end cover 112 , which is connected to the end of the motor housing away from the first end cover 111 , and is used to limit, fix and protect the end of the motor assembly 200 away from the reducer assembly 300 .

[0076] Exemplarily, the electric drive system 10 may further include a thermal management water jacket 130, which is arranged inside the first shell 110 and around the motor assembly 200. A water flow channel may be formed between the thermal management water jacket 130 and the inner wall of the first shell 110 for passing cooling water to dissipate heat from the motor when the motor assembly 200 generates heat during operation.

[0077] It should be noted that the motor assembly 200 may include a rotor and a stator, the stator is connected to the thermal management water channel, and the rotor is connected to the output shaft 210 .

[0078] In some embodiments, the input end of the reducer assembly 300 is connected to the output shaft 210, and the reducer assembly 300 can be a planetary reducer or a parallel gear reducer.

[0079] For example, the reducer assembly 300 may be a planetary reducer, and the electric drive system 10 may further include a transmission shaft 400. The output shaft 210 has a connecting hole extending through both ends, and the transmission shaft 400 is disposed through the connecting hole. The transmission shaft 400 is connected to the reducer assembly 300 so that the input and output ends of the reducer assembly 300 are coaxial, thereby improving space utilization within the electric drive system 10 and reducing the overall size of the electric drive system 10.

[0080] The present invention also provides a vehicle that can include the electric drive system 10 of the above technical solution. The vehicle provided in the present invention can be a new energy vehicle, including but not limited to a pure electric vehicle, a hybrid electric vehicle, a hydrogen-powered vehicle, etc., which is not specifically limited in the present invention.

[0081] The vehicle provided in the embodiment of the present application has all the technical solutions and all the technical effects of the aforementioned electric drive system 10, which will not be repeated here.

[0082] An embodiment of the present application provides an electric drive system 10, which includes a first shell 110, a second shell 120, a motor assembly 200 and a controller assembly 500. The first shell 110 has a first accommodating cavity 101, and the motor assembly 200 is arranged in the first accommodating cavity 101; the top of the first shell 110 has a accommodating groove 103; the second shell 120 is covered above the accommodating groove 103 and is surrounded by the accommodating groove 103 to form a second accommodating cavity 102, and the controller assembly 500 is located in the second accommodating cavity 102. The controller assembly 500 is connected to the side of the second shell 120 facing the accommodating groove 103, so that the assembly of the controller assembly 500 is completed by docking the first shell 110 and the second shell 120. The controller assembly 500 is installed on the second shell 120, and the arrangement of the controller assembly 500 utilizes the accommodating space on the first shell 110, thereby reducing the volume of the electric drive system 10 and reducing the weight of the electric drive system 10.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
